How to connect a Sam4S printer via USB on Windows or macOS
Set up an ESC/POS Sam4S printer to work over USB.
To print receipts, checks before closing the order, kitchen tickets, and delivery receipts, connect the Sam4S printer to your device running the Poster app:
- Plug the printer into a 220V power outlet.
- Connect the printer to your Windows or macOS computer or all-in-one using a USB 2.0 AM-BM cable.

- Open the Poster app and enter your employee PIN code.
- Tap ≡ in the top right corner and select Devices.
- Wait for the search to complete, then select the printer from the list and choose what it will print:
— Receipt — if this printer is for printing guest receipts.
— Stations — select the kitchen stations this printer will print tickets for, for example "Bar", "Kitchen", or "Hot kitchen". - Tap Print test receipt.
💡 The printer driver will be installed automatically.
